RAILROAD-TIE.

Specification of Letters Patent. I Patented Sept. 3, 1912.

Application filedJune 27, 1911. Serial No. 635,526.

To all whom it may concern."

Be it known that I, SIGMUND FRIEDMAN, a citizen of the United. States,residing at Gorgona, Canal Zone, Panama, have invented new and usefulImprovements in Railroad-Ties, of which the following is aspecification. v

The present invention relates to railroad ties and has particularapplication to certain novel and useful improvements in re inforcedconcrete ties.

In carrying out my invention, it is my purpose to provide a railway tieembracing the desired. features of simplicity, durability and strength,coupled with cheapness of cost in manufacture and installation.

A further object of my invention is the body of metallic mesh, myconstruction further embodying tie members extending insuch manner as toembrace the base or plates of the rail chairs.

Furthermore, I aim to provide a novel arrangement of means carried bythe concrete tie for supporting the rails positively and safelyin'position.

Another object of the invention is to protie which while possessing manyof the advantages of the ordinary wooden tie, such as a certain amountof elasticity, will not be subjected to the disadvantage of rapiddestruction and decay, due to the action of the elements and otherwellknown factors which tend to shorten the life of the ordinary tie.

With the above-recited objects and others of a similar nature-in view,the invention consists in the construction, combination and arrangementof parts, set forthin and falling'within the scope of the appended Inthe accompanying drawing :-Figure I is a perspective view of a railwaytle embodying my invention, showing the manner of securing the railsthereto. Fig. 2 is a view inside elevation of the metallic reinforcingmesh, and showing the same carrying the rail chairs. Fig. 3 is avertical my improved tie. Fig. 4 is a vertical cross sectional view onthe line H of Fig. 1. In thepresent instance, I have shown ajnnent of myinvention wherein the tie comprises an oblong reinforcing body of wiremesh-or the like,

plates of the chair rails, these being secured in position by boltspassing through the reinforcing body and the .base of the chair rails,said reinforcing body being embedded in or coated with a body of cement,so that illnstratiomas modification and'variationmay be made withoutdepartingfrom the spirit of the invention or exceeding the scope of theappended claims.

Referring now to the accompanying drawings in detail, the numeral 1designates the reinforcing body which is in the nature of an oblongstructure formed of metal having openings therein, such as wire mesh orthe like, thefree longitudinal edges of the reinforcing body being bentinward and downward at the top thereof, as shown at 22. Extendinglongitudinally through the reinforcing body are the tie rods 3, the endsof which are curved upward as at 4, to project through the openings inthe mesh at the top, the ends being then curved inward as at 5, to formhooks for engaging with the notches 6 in the adjacent edges of the railchairs 7-8. The chair 7 is formed with a flat base or section 8. havingdownturned flanges 9 at the longitudinal edges thereof and upon thisbase is formed a vertical flange or stop 9 from the central of whichextends upwardly the slightly inclined member 10' cut away at its baseas at 11 for the reception of the base of the rail the face 12 of saidmember being adapted to engage with the web of the rail. ()n theopposite sideof the rail. is a clamping member 13 having a shoulderedend 14 for engaging with the adjadi-nt portion of the rail base, while15 indictttcs a bolt extending vertically thron h the tie, rail chairand clamp 13, a nut 6 being threaded onto the endof the beltfor holdingthe clamprigidly in position.

The rail chair 8 is formed of a plate or base section 17 having thedownturned flanges 18, while upon top'of the base is a vertical flange19 against which abuts the side of the rail base, while 20-20 desi latebolts passing upward vertically throng the "ti'e,'ra1l chair andclamping members 2121 arranged at opposite sides of the rail base,

upon the upper side ofwhich I mount the the clamping members havingshoulders 22 also holding the clamps or retaining clips.

. through the openings of rovide longitudinally extending substantiallyvertical spaced walls, the said top of the reinforcing body beingpositioned adjacent the top of the concrete body and being provided withflanged edges which engage with the longitudinal sides of the concretebody, and means embedded within the concrete body and arranged betweenthe sides and the downturned walls of the reinforcing bodyand engagingwith the chairs for sustaining the said chairs upon the tie.

3.'A. railway tie comprising a body of concrete or similar material, areinforcing body of pervious metal-bent to provide a substantiallyrectangular body embedded therein, the edges of the said reinforcingbody being arranged at the top thereof and being bent downwardly withinthe body to provide longitudinally extending substanengaging with therail base, said clamping members being secured to the projecting ends ofthe bolts by the nuts 23.

The rails of the track are indicated at The concrete body of the tie isindicated by the letter C, and in manufacturing the reinforcement isembedded in and completely covered with the body of concrete, theconcrete in its plastic state working in the mesh and completely fillingthe inside of the oblong mesh body' hile the concrete also covers theentire outside of the reinforcement, the plates of the rail chairs lyingflush with the top face of the concrete of the tie, while the downwardlyturned side flanges of the chair plates are flush with and embedded inthe vertical sides of the concrete body. The

sides which are indicated at 24-2 t are tially vertical spaced walls,the said top of slightly tapered downward and inward to the reinforcingbody being positioned adprevent the tie from sinking sidewise in thejacent the top of the concrete body and being provided with flangededges which engage with the longitudinal sides of the concrete body,means embedded within the concrete body and arranged between the sidesand the downturned walls of the reinforcing body and engaging with thechairs for sustaining the said chairs upon the tie, rail clamps upon therail chairs, an both members passing through both of the bodies of thetie and between the downturned ends of the reinforcing body forretaining the clamps upon the chair.

4. A railroad tie comprising a body of concrete and a body of wire meshwhich is bent into tubular form and which is embedded within theconcrete body, the edges of the reinforcing member being extendeddownwardly within the concrete body adjacent the top thereof, a railchair resting upon the reinforcing body and having its edges providedwith flanges which engage with the concrete body, tie rods within theconcrete body having curved ends formed with inturned portions whichpass through the bodies of the tie and which engage with the edges ofthe rail chair, headed bolts embedded within the concrete and passingthrough the chair between the downturned portions of the reinforcingbody, rail clamps adapted to co-act with the bolts and nuts forretaining the rail clamps uponthe chair and upon the bolts.

In testimony whereof I affix my signature in presence of two witnesses.

round, while the ends of the ties are molded with holes 25- 25 tolighten the weight of the tie and to provide means whereby the tie maybe easily carried, by the insertion of bars or rods therein.

From the above description taken in connection with the accompanyingdrawings, the construction and manner of employing my improved rail tiewill be readily apparent. It will be noted, that I provide a reinforcedconcrete tic which, owing to the peculiar character of thereinforcement, is capable of yielding to the shocks and jars of therolling stock passing thereover, much in the manner of the ordinarywooden tie. In addition, by forming the chairs practically as anintegral portion of the tie and securing the chairs in position asshown, provide against the accidental loosening and disengagement of thelatter, the same means which secure he chair in position at its base Iclaim 2- 1. A railway tie comprising an inner body and an outer body,said inner body being formed of a resilient member formed with holes,flanged rail chairs resting upon the said inner body, tie rods havingcurved inner ends and inturned portions engaging with the rail chair,and said outer body being formed of plastic material within which theresilient inner body is embedded.

2. A railway tie comprising a body of concrete or similar material, areinforcing body of pervious metal bent'to provide a substantiallyrectangular body embedded therein, the edges of the said reinforcingWitnesses:
